Drawing Polygons 
A polygon consists of one or more closed sequences of connected 
line segments (which may cross each other). Drawing polygons 
requires the use of the polygon mode. The Polygon Mode (PM) 
command tells the printer to store subsequent commands and 
coordinates in the polygon buffer before printing the shape. 
(Rectangles and wedges are polygons which have their own 
drawing commands; the printer automatically generates and 
stores the coordinates in the polygon buffer.)
You can use the following commands in polygon mode to create 
polygons. These commands are stored in the polygon buffer until 
they are replaced with another polygon or the printer is initialized.
